b4 - working memory model Flashcards
what was the major problem with the multi store model?
the STM is far more complex than suggesting in the model
the stores were described as single units
what’s the difference between the multi store model and working memory model?
WMM explains STM as a more active process than the MSM
what are the four components of working memory?
central executive
phonological loop
visio-spatial sketch pad
episodic buffer
what is the central executive?
‘supervisory role’ monitors incoming data it focuses and divides our limited attention and allocates ‘slave system’ to tasks. has limited processing capacity does not store information
what is the phonological loop?
a slave system
deals with auditory information and preserves the order in which the information arrives
what are the two subdivisions of the phonological loop and what do they do?
the phonological store - stores the words you hear
the articulatory process - allows maintenance rehearsal, capacity of the loop is two seconds worth of words you can say.
what is the visio-spatial sketch pad?
a ‘slave system’
stores visual and/or spatial information
it has a limited capacity of about 3-4 objects
what are the two subdivision of the visuo-spatial sketch pad and what do they do?
the visual cache - stores visual data
the inner scribe - records the arrangement of objects in a visual field
what is the episodic buffer
a ‘slave system’ was added into the model later, a temporary store for information, integrating the visual, spatial and verbal information processes by other stores and maintaining a sense of time sequencing. limited capacity of 4 chunks. it links working memory to LTM
two strengths of the working memory model
support from other studies - Shallice and Warrington
dual-task performance support
name a study that supports the Working memory model
Shallice and Warrington (1970)
explain Shallice and Warringtons study
case study of patient KF who suffered from brain damage, impaired his STM, auditory information recall poor (damage to phonological loop) vs visual information recall unaffected (no damage to visuo spatial sketch pad)
